AC ETYLEN E-GAS G EN ERATO R.

SPECIFICATION forming part of Letters Patent No. 625,735, dated May 30, 1899. Application filed February 18, 1899- Serial No. 705,986. (No model.)

To all whom it may concern."

Be it known that I, HANS BERGER, a subject of the Emperor of Germany, residing at Berlin, Empire of Germany, have invented a certain new and useful Improved Apparatus for Generating Acetylene Gas, of which the following is a full, clear, and exact description.

The present invention relates to apparatus for generating acetylene gas; and it consists in constructing the apparatus so that a certain quantity of calcium carbid shall be periodically and automatically precipitated into the water, the gas generated raising the gasometer-bell, which on sinking below a certain point will again precipitate a further quantity of carbid into the water of the generator. The device for throwing the carbid into the water is constructed so as to throw as little work as possible onto the gasoineter-bell, a

very light touch of the same beingsufficient to empty the carbid-receptacle.

In order to render the present specification more easily intelligible, reference is had to the accompanying drawings, in which similar letters of reference denote similar parts throughout the several views.

, Figure 1 is a vertical section throughthe generator and a part of the gasometer. Fig. 2 is a plan view of the generator with the cover removed, and Fig. 3 is a detail of the runner operated by the sinking bell to upset the carbid-receptacles successively.

A is the generator, having a suitable cover B. The carbid-receptacles C may be of any convenient shape, but are advantageously made tapering toward the top, as shown at Fig. 2, the bottom plate forming a downwardly-opening cover F, hinged at E and provided with a forwardly-projecting stem D. At one of the ends of the top of the chamber or receptacle the same is suspended in suitable manner-for instance, by means of a hook and hinge-pin,as at Hto the inner wall of the generator, near the top of the same, above the surface of the water. The receptacles are arranged in a ring, as shown at Fig.

. 2, their pins D all resting on a disk K. The

latter is mounted on a vertical spindle S, supported by means of a collar on a frame S and passing downwardly through a sleeve T, having stufiing-box N and gland R at the bottom cd when the bell sinks to press the runner,

or,more properly speaking, stop Z on the cord P, and to turnthe roll I a certain part of a revolution. This movement will correspondingly rotate the disk D. The disk D is provided with one or more slots 0 in its circumference, whichare long enough to allow the pin D of the cover of a carbid-receptacle to fall through when the slot is turned under one of thepins. In Fig. 2 twosuchslotsare shown, which are so arranged that a very slight turn of the'disk will bring one or other of them alternately under one pin of a carbid-receptacle,as will be evident on reference to the drawings. The stop on the cord P is provided with a spring-catch or other suitable mechanism, Fig. 3, which allows it to be moved freely upward along the cord, but when pushed down it will gripthe cord and turn the roll or pulley I. The gas generated in the generator .passes through the pipe U to the gasometer.

The device operates in the following manner: The carbid-receptacles are all filled and suspended in position in the generator, with the pins of their covers F resting on the disk K. The cord P is then moved by hand to start the apparatus until one carbid-charnber is upset, the gas generated raised the bell M, and the stop Z is then adjusted to a certain distance above the lowest point of the gasometer-bell. As soon as the gas in the bell has been exhausted the latter in sinking touches the stop Z, lowering the same and turning the roll I so as to bring one or other of the slots 0 underthe'pin of another'receptacle. A second carbid-cha nber is emptied into the water and the bell again rises. The next time it will have to sink somewhat farther before it again reaches the stop, so

ICCI

that the latter should'in the first place be adjusted to a position high enough to allow it through the slot not only will the cover F fall down, but the receptacle will drop, withits lower edge swinging around the pin H, and.

will thus be shaken, so that all the carbid will be thrown out. lieves the gasometer-bell of heavy work, since Very little power or weight is required to turn I the roll I.

I claim as my invention-'- 1. In an acetylene-gas generator, the combination of a series of carbidchambers suspended at their upper back edge to the interior of the Wall of a generator, said chambers having downwardly-opening covers, and horizontally-projecting pins thereon, a rotary disk having one or more slots therein, said disk being horizontally disposed and adapted to support the pins of all the carbid-chamber covers, said slots being so located that a pin of a cover may fall through when the said disk is partially turn ed and means in connection with the gasometer-bell to turn said disk This construction rewhen the gasometer sinks below a certain point substantially as described.

2. In an acetylene-gas generator, the com bination of a series of carbid-chambers suspended around the interior of the generator as specified, said chambers having hinged covers with pins thereon and a disk having slots as specified to support the pins of all the covers and retain the chambers closed when charged, a vertical spindle to support said disk, a sleeve mounted within the generatorand having stuffing-box and gland, through which said spindle passes out of the generator, a pulley mounted on the lower end of said spindle and a cord passing around said pulley, a fork or finger on the gasometer-bell and means for guiding said cord in the path of movement of said fork or finger and a stop on said cord adapted to be engaged by said finger or fork in the manner and for the pur pose substantially as described.

In witness whereof I have hereunto set my handin presence of two witnesses.

HANS BERGER.
